Dual Killing-Yano symmetry and multipole moments in electromagnetism and mechanics of continua

In this work we introduce the Killing-Yano symmetry on the phase space and we investigate the symplectic structure on the space of Killing-Yano tensors. We perform the detailed analyze of the $n$-dimensional flat space and the Riemaniann manifolds with constant scalar curvature. We investigate the form of some multipole tensors, which arise in the expansion of a system of charges and currents, in terms of second-order Killing-Yano tensors in the phase space of classical mechanics. We find some relations between these tensors and the generators of dynamical symmetries like the angular momentum, the mass-inertia tensor, the conformal operator and the momentum conjugate Runge-Lenz vector.Comment: 11 pages LaTeX, no figures, content enlarged and revised, accepted for publication in Helvetica Physica Act

CASH FLOW REPORTING AND CREATIVE ACCOUNTING

Within the wide field of creative accounting, the main preoccupation of researchers surrounded earnings management. The current study comes to acknowledge that creative cash flow may distort the assessment of financial performance and should therefore, become a subject of the same interest for analysts and investors, as earnings management is. In order to reach the objective proposed, there are two hypotheses formulated, to be validated within the research: H1: Creative accounting distorts cash flow reporting within the boundaries of current regulations. H2: Real activity manipulation alters significantly the operating cash flow. The steps followed were analyzing the accounting standard related to cash flow statement, IAS 7, in order to uncover issues not taken into account, or options of allocation provided for accountants, which could lead to opportunistic choices and lack of comparability. The relevant literature was reviewed, so as to identify the opinions of accounting and finance specialists related to this subject, the results of their scientific process. The final step was a synthesis of relevant results and observations, which lead to the acceptance of the hypothesis of the research. Moreover, several techniques were identified, both related to creative accounting and to real activity manipulation, influencing mainly the figure reflecting operating cash flow, and thus the image on the potential of business continuity. Main conclusions were that the techniques applied were within the limits set by the standard: opportunistic allocation of dividends and interest collected or paid misallocation of certain activities like sale of receivables, but mainly recording non-recurring events into the operating cash flow, without separate notes of information or adjustments. Real activity manipulation should also be considered as it is even more difficult to detect, unless analysis is also performed on notes to financial reports and the figures within the profit and loss account. The contribution of the current study is providing a synthetic arrgumentation to why cash flow should be analysed in the context of creative accounting, reviewing methods and techniques that distort significantly the results of operating activity, providing basis for further study related to the impact of such practices on forecasts of cash flow and predictability of bankruptcy.operating cash flow, creative accounting, non-recurring activity, IAS 7, financial performance

FREE CASH FLOW AS PART OF VOLUNTARY REPORTING. LITERATURE REVIEW

The present study has as main objective to reflect the state of literature regarding free cash flow, and to withdraw the main pro's and con's in order to create an objective image upon this indicator. The main idea generating this research was the growing interest on cash flow reporting. As many say, "Cash Flow is King", while in Anglo Saxon countries the interest of investors and analysts in concentrated on operating cash flow, as the most important indicator of the probability of bankruptcy. In this context, voluntary additional reporting, like free cash flow may come either as an aid in providing the fair view or as an opportunistically reported figure. Throughout the paper, the intention was to provide answers to three main research questions: "What are the definition and calculation method of free cash flow? Why is there an interest in free cash flow reporting? What is the impact of free cash flow on the agency theory?" In order to provide relevant conclusions, four international data basis were used, and related articles and studies were extracted. The results proved that there is no generally accepted definition and computing method, while the format depends on the end-user of the report (shareholders, investors, analysts, bankers, a.s.o.). As stated below, this aspect generates confusion and lack of comparability, giving room to creative accounting techniques. Moreover, the interest on free cash flow reporting is connected mainly to liquidity assessment, company valuation and investors' choice. Still, in the context of agency theory, results show that in presence of high free cash flow, managers tend to make investment choices that satisfy their personal interest and that generate low efficiency and profitability for the company. The contribution to current state of research is providing a literature review study, focused on a comparative approach, as well as on underlying an objective image upon a debatable financial indicator and accounting report.free cash flow, reporting, management, agency theory, creative accounting

FROM THE HARMONIZATION NEED TO THE SPONTANEOUS ACCOUNTING HARMONIZATION

The issue of international accounting harmonization has achieved, mainly within the last decade, a significant dimension in the field of international accounting research. The main determinant factor for this state of the art is the process aiming at red

Influencing the physiology and decisions of groups: Physiological linkage during group decision-making

Many of the most important decisions in our society are made within groups, yet we know little about how the physiological responses of group members predict the decisions that groups make. In the current work, we examine whether physiological linkage from “senders” to “receivers”—which occurs when a sender’s physiological response predicts a receiver’s physiological response—is associated with senders’ success at persuading the group to make a decision in their favor. We also examine whether experimentally manipulated status—an important predictor of social behavior—is associated with physiological linkage. In groups of 5, we randomly assigned 1 person to be high status, 1 low status, and 3 middle status. Groups completed a collaborative decision-making task that required them to come to a consensus on a decision to hire 1 of 5 firms. Unbeknownst to the 3 middle-status members, high- and low-status members surreptitiously were told to each argue for different firms. We measured cardiac interbeat intervals of all group members throughout the decision-making process to assess physiological linkage. We found that the more receivers were physiologically linked to senders, the more likely groups were to make a decision in favor of the senders. We did not find that people were physiologically linked to their group members as a function of their fellow group members’ status. This work identifies physiological linkage as a novel correlate of persuasion and highlights the need to understand the relationship between group members’ physiological responses during group decision-making

Motivating Accounting Professionals in Romania. Analysis after Five Decades of Communist Ideology and Two Decades of Accounting Harmonization

Our paper focuses on accounting professionals in Romania as being a significant element when considering a national accounting system that went through complex accounting reforms of more than two decades. Since accounting policy represents an area of social and economic policy we must also consider the five decades of communist regime leaving their fingerprint on the Romanian society. It is our objective to capture the perception of the Romanian accounting profession that actually witnessed all these processes of transformation. More precisely we focus on exploring the motivational pattern of Romanian accounting professionals, arguing that our results could offer useful insights when it comes to accountants’ drivers to participate in the international accounting arena and therefore in the international accounting harmonization process. Our theoretical framework is based on Herzberg’s motivation-hygiene theory. Since Herzberg in his studies used the interview method, for more consistency, we found an interview-based qualitative approach to be the most appropriate to our research. One of our conclusions is that Herzberg’s theory can identify and explain reasonably well the motivational factors of today’s Romanian accounting professionals. However, the theory must be adjusted for higher relevance: (1) salary is not seen hygiene but a motivator, (2) advancement is not a motivator but hygiene, and (3) team/staff with strong motivational effect must be added to the model. Motivators and Hygiene factors were directly related to the level of hierarchy and redrafted a different pattern within the structure of an entity. By analyzing the information being obtained through the interview process, our paper offers an overview on the particular work environment that characterizes the accounting professional of late Romanian modernity, after five decades of an ideology based system. The results of the performed analysis document the fact that alienation and dependence have not become characteristics of the modern accounting professional. Furthermore, dehumanization and exploitation prove to be, in the case of the Romanian accounting system, inevitable consequences of the division of labor and the development of private property.Drivers, Motivators, Hygiene Factors, Job Satisfaction, Labor Behavior, Organizational Culture, Human Resource Accounting
